ELEUTJEtICAL ATTACHMENT FDR HAY-PRESSES.

To all whom it may concern:

Be it known that I, WALTER D. GLADNnY, a citizen of the United States, residing at Sile in the county of Lincoln and State of Missouri, have invented certain new and useful Improvements in Electrical Attachments for Hay-Presses, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to baling presses, and it more particularly relates to an electrical attachment for hay presses.

One of the objects of this invention is to provide a hay press with an electric bell and with means for automatically ringing the bell when each hay-bale has been completed.

Another object of the invention is to provide an attachment which may be secured on hay-bales of ordinary construction and of diii'erent kinds, and which may be adjusted thereon, for regulating the size of the haybales to be made.

Another object of the invention is to pro vide a device of this character which is simple in construction, comparatively inexpensive, compact, durable, and thoroughly practical and efiective in operation.

In the accompanying drawings which supplement this specification, Figure 1 is a side elevation of a hay-press embodying the improvements of my invention. Figs. 2 and 3 are fragmentary plan views showing parts in different positions; and Fig. 4 is a longitudinal sectional view.

In these drawings, in which similar reference characters correspond with similar parts throughout the several views, the frame 10 of an ordinary hay-baler is somewhat diagrammatically illustrated, and on each vertical side of this frame is secured one of the attachments which constitutes the present invention; although, if desirable, I may employ but one of these attachments, which are generally designated by the numeral 11, with the hay baler. Each of these attachments comprises a frame consisting of a pair of vertical clamping bars 12, each of which is provided with elbows or lateral eX- tensions at its opposite end. These extensions 13 are each apertured for the reception of a set screw 1.4:, and thereby adapted to be clamped upon the top and bottom edges of the frame 10. The frame 11 further comprises a pair of horizontal and parallel bars 15, having their respective ends rigidly se- Specification of Letters Patent.

cured to the clamping bars 12. An electrical contact member 16 is hingedly connected at 17 to each 01' the bars 15, and a bolt 18 connects each member 16 in movable relation tothe contiguous bar 15, so that the members 16 may have limited movement on their hinged connections 17, but are held in their respective horizontal planes. Each member 16 is preferably formed in two sections, 16 and 16, respectively, an insulating element 19 being disposed between the contiguous ends of the sections. The member 16 is bent outwardly, so as to term a cam-surface on its inner side. A spring 20 is provided on the bolt 18 and this spring actuates the member 16 for moving and holding it inwardly of the baling-press.

An arm or support 21 is rigidly secured on the frame 11, and a stationary contact element or metal rod 22 has its medial portion secured to the support 21 and extends upwardly and downwardly therefrom, so as to lie in the path of the movable contact members 16, and lying between these contact members and the interior of the baling-press.

The baler-head or head-block 23 is provided with a metal contact plate 24, which is adapted to be moved into the path of the members 16 and to contact with these members, as hereinafter explained.

An electric battery 25, which may be of any proper and preferred kind, is electrically connected with a bell 26; this bell and battery being located and supported on any convenient portion of the baling-press. The bell and battery are connected to the members 15 at their respective ends, as indicated at 27, by means of suitable conductors 28. The bell and battery are normally out of circuit, the switch 29 being open. However, this switch is closed when the baling-press is to be used, so that when the partially formed bale of hay is opposite to and in contact with the cam-surfaces 16, the members 16 are swung outwardly on their hinges, against the action of the springs 20, so as to break the contact between these members 16 and the members 21 and 24. However, when the bale has been completed, and the head-block 23 has moved into a position opposite to the spring contact element 16, the springs 20 move these elements 16 into contact with the rod 22 and the plate or strip 24;, so as to close the circuit and ring the bell, thereby signaling the operator that the bale is now completed and that it is time to put in another headblock to make another bale.

By means of a device of this character, it will be seen that the bales may be made of a very uniform size and weight, and it will also be seen that the size and weight thereof may be varied by changing the position of the frame 11 on the ba-ling-press frame.

From the foregoing description, it will be seen that I have provided a device of this character which is fully capable of attaining the desired objects, as specified.

lVhile I have described the preferred embodiment of my invention, it is to be understood that the invention is not limited thereto, but that various changes may be made in the form, proportion and arrangement of the parts, without departing from the scope of the appended claims.

Having thus described this invention, what is claimed is 1. In an attachment for a baling-press comprising spaced bars adapted for adjustable engagement with the press, cross bars uniting the first mentioned bars, an elongated stationary contact member con nected to one of the first mentioned bars and disposed to one side thereof, contact arms carried by the cross bars movable relatively thereto and disposed across the stationary contact, a source of electrical bars.

2. In an attachment for a baling-press comprising spaced bars adapted for adjustable engagement with the press, cross bars uniting the first mentioned bars, an elongated stationary contact member connected to one of the first mentioned bars and disposed to one side thereof, contact arms carried by the cross bars movable relatively thereto and disposed across the stationary contact, a source of electrical supply, connections between such electrical source and the extremities of the movable contacts, and means for automatically maintaining the movable contacts in engagement with the stationary contact, said movable contacts being provided with means whereby they may be moved out of engagement with the stationary contact.

In testimony whereof I hereunto afliX my signature in the presence of two witnesses.
